Merging different position (length) lines ??

As shown above, when lines 1 and 2 are different in length and position, they merge.

Do you have any mathematical methods or other methods? I think that's what happens when we merge.

Can you do this in the matlab?

My English is not good. I'm sorry.

Although the two curves look different in length and position, technically, curve one still have values (all zero) at the begining and curve two have values (all zero) at the end.

As long as you can make the data (time and value) for the two curves the save length and at the same time point, you can just add the value together.

Could you write me a matlab code that combines two lines with different positions?
